a corporation of Ohio Filed July 14, 1958, Ser. No. 748,343 8 Claims.(Cl. 105409) This invention relates to side wall structures forinsulated railway cars.

It is an object of this invention to provide metallic side wallstructures for insulated railway cars which shall permit more eflectiveuse of the insulation employed in the side wall structures.

A further object is to provide metallic side wall structures forinsulated railway cars which shall minimize the amount of voids in theside Walls.

A further object is to provide side wall structures for insulatedrailway cars which shall embody metallic intermediate posts andsheathing wherein the posts are so related to the sheathing as to permita more complete development of the insulating value of the insulationused in the side wall structures.

A further object is to provide welded metallic side wall structures forinsulated railway cars which shall embody intermediate posts andsheathing wherein the sheathing adjacent to the posts shall be so formedas to reinforce the sheathing, prevent buckling normally resulting fromwelding and break up the monotony of appearance of the side wallstructures.

A further object is to provide welded metallic side wall structures forinsulated railway cars which shall embody intermediate posts andsheathing wherein the posts shall be so conformed as to lie partlyinwardly and partly outwardly of the plane of the sheathing.

A further object is to provide welded metallic side wall structures forinsulated railway cars which shall embody intermediate posts andsheathing wherein the posts and sheathing shall be of such configurationthat a portion of the posts shall project outwardly beyond the plane ofthe sheathing and be received Within the conformations formed in thesheathing.

A further object is to provide novel intermediate posts for the sidewall structures of insulated railway cars.

A further object is to provide novel intermediate posts for the sidewall structures of insulated railway cars which shall be at least asstrong as the intermediate posts in general use and permit a decrease inthe projection of the posts into the cars.

Other objects of the invention will become clear as the descriptionthereof proceeds.

In the drawings forming part of this specification:

FIG. 1 is an elevation of a portion of a side wall structure forinsulated railway cars embodying the instant invention.

FIG. 2 is a horizontal section taken on FIG. 1.

FIG. 3 is a horizontal section taken on line 3-3 of FIG. 1.

FIG. 4 is a vertical section taken on line 4-4 of FIG. 1.

FIG. 5 is an elevation of a portion of a side wall structure forinsulated railway cars embodying a modification of the invention.

FIG. 6 is a horizontal section taken on line 6-6 of FIG. 5.

FIG. 7 is a horizontal section taken on line 77 of FIG. 5.

KG. 8 is a vertical section taken on line 3-8 of FIG. 5.

Referring first to the embodiment of the invention illusline 2-2 oftrated in FIGS. 1, 2, 3 and 4, the numeral 10 designates a portion of aside wall structure for insulated railway cars 5 extending substantiallyfrom the door opening 11 formed in the structure to the adjacent end ofthe structure. It will be understood that the remainder of the side wallstructure is complementary to the portion illustrated and is ofsubstantially the same construction.

The side wall structure 10 embodies a customary side plate 12 includingan outward, downwardly extending flange 13, an angle side sill 14 havingan upstanding leg 15 in substantially vertical alignment with thedepending flange 13 of the side plate corner and door posts 16 and 17which may be of any desired construction and intermediate posts id. inthe considered embodiment of the invention each of the intermediateposts 18 has a web 19 which as is more clearly shown in FIG. 4 of thedrawings extends between and is secured as by means of welding to theopposed edges of the depending flange 13 of the side plate and theupstanding leg 15 of the side sill. The sides of the web 1d are inclinedoutwardly in opposite directions to provide flanges 29 and 21. Theseflanges are turned inwardly to provide flanges 22 and 23 which arespaced from the sides of the web 19. The flanges 22. and 23 extendinginwardly beyond the web as shown more clearly in FIG. 2 of the drawings.These flanges in turn are bent outwardly in opposite directions toprovide inclined flanges 24 and 25 which lie inwardly of the plane ofthe web 19.

The described structure of the intermediate post 18 thus providesformations 26 and 27 which embody the inclined flanges 2i? and 21 andportions of the inwardly turned flanges 22 and 23 that lie outwardly ofthe plane of the web. As shown more clearly in FIG. 4 of the drawingsthese formations merge as indicated at 28 and 29 into the plane of theweb 19.

Metallic sheathing 30 is secured to the outside of the intermediate,door and corner posts and to the outside of the flange 13 of the sideplate and leg 15 of the side sill. The metallic sheathing extendssubstantially to the middle of the Webs 19 of the intermediate posts towhich the sheathing is welded by a single line of weld as indicated at31. Where the sheathing crosses the conformations 2d and 27 it is oflsetoutwardly as indicated at 32 and 33 to provide portions within which theconformations 26 and 27 are received.

The upper and lower edges of the metallic sheathing are adgned so thatit may be welded to the side plate and side sill by automatic weldingdevices. In this welding operation the outwardly offset portions 32 and33 of the sheathing will prevent buckling thereof. In addition theseoutwardly oflsct portions serve to reinforce the sheathing and to breakup the customary monotony of side wall structures of insulated railwaycars. The outwardly oliset portions 32 and 33 of the metallic sheathingmerge into the plane of the sheathing as shown at 34 and 35 so that theautomatic continuous lines of welding 36 and 37 may be utilized.

it follows from the relationship between the intermediate posts and sideplate and side sill as shown in FIG. 4 of the drawing that the web 19and conformations 26 and 27 of the posts terminate at the flange 13 andleg 15. The remainder of the inwardly extending flanges 22 and 23 andthe inclined flanges 24 and 25, however, are continued upwardly as shownat 3% and downwardly as shown at 39 upon the inside of the flange 13 andleg 15 and are welded thereto.

Side wall structures for these cars are insulated. To

insulate the hereinabove described side Wall structure, it is preferredto place a wooden timber 40 against the in-' amazes intermediate posts.To secure the insulating material to the timbers '40 vertically spacedblocks 42 are secured against the inner face of the insulating materialby means of Nelsonstuds S welded to the webs 19. These studs extendthrough openings provided in the timbers 4t? and through the blocks 42and by means of nuts threaded upon the inner ends of the Nelson studs.These blocks are forced against the insulating material so as tocompress ing material is preserved between the vertically spaced blocks42 as shown more clearly at 44 in FIG. 3 of the drawings. This is madepossible by the design of the in termediate posts 19 whereby a portionof the posts extends outwardly beyond the plane of the metallicshe-athing while a portion thereof extends inwardly of this plane.Accordingly while the indicated highly desirable result of moreeffective insulation is secured, its accomplishment is obtained withoutsacrificing any of the strength of the posts. 7

Moreover, by inclining the flanges 24 and 25 as shown in FIG. 2 of thedrawings the size of the voids created by these flanges is reducedthereby maintaining the full thickness of the insulation to the greatestpossible degree. He cumulative "eifect of the construction hereinabovedescribed is to reduce materially the hot spots which are normally foundin the usual side wall constructions of insulated railway cars and whichadversely affect the insulating value 'of the side walls.

A second layer of insulation 45 is customarily used in the side walls ofinsulated railway cars. With reference to FIG. 4 of the drawings, itwill be seen that this layer of insulation is formed of sections whichare retained between longitudinally extending timbers 46 and 47 securedin place by being bolted to the spaced blocks .2 as by means of bolts 48and 49. This insulationis retained in place by means of aplywood innerlining 50 nailed to the timbers 46 and 47. The plywood serves to supportan inner plywood cold wall 51 which is customarily nailed theretothrough spacer blocks (not shown).

A modified form of intermediate post is illustrated in FIGS. 5 to 8,inclusive, of the drawings. With the exception of the difierence in theintermediate post the side wall illustrated in these figures is the sameas that shown in the embodiment of the invention illustrated in FIGS. 1to 4, inclusive; The considered intermediate post which is indicated bythe reference numeral 52 is formed with a Web 53 the sides of which areturned inwardly to form flanges 54 and 55 which in turn are bentoutwardly to provide flanges 56 and 57 lying substantially parallel tothe web. Intermediate the inturned flanges 54 and 55 the web 53 ispressed outwardly to provide a vertically extending channel portion 58.-At its upper and lower ends the channel portion 58 merges into the planeof the web as indicated at 59 and 60 and together with the web 53extends between the opposite edges of the flange 13' of the side plateand leg of the side sill and is welded to this flange and leg. Theflanges 54 and 55 and 56 and 57, however, continued upwardly anddownwardly upon the inside of the flange 13 and leg 15 as shown at 61and 62 and are weld ed to the inner faces of the flange and theupstanding leg.

To complete the metallic side wall structure sheathing '63 is secured asby means of welding upon the outside of the webs '53, flange 13 and leg15. The sheathing terminates on either side of the channel-shapedportions 58 and as in the case of the first described embodiment of theinvention may be welded to the webs by continuous automatic welding.Moreover, a continuous automatic weld may be employed to secure theupper and lower edges of the sheating to the flanges 13 and 15.

With the exception of the somewhat greater amount of voids which areoccasioned by the flanges 56 and 57 the side wall structure describedimmediately above also decreases the hot spots in the insulated sidewall structure and substantially enhances the insulating value of thewall. This is made possible by the design of the intermediate post andits disposition relative to the plane of the sheathing. In thisaccomplishment no loss in the strength of the post occurs. Both of theposts herein described are at least as strong as the intermediate postsheretofore used; In the last considered embodiment of the invention theNelson studs S are welded to the outwardly extending channel portion 58.7

As shown in FIGS. 7 and 8 a substantial portion of the insulatingmaterial is provided by the invention between the vertically spacedblocks as shown at 64.

it will be apparent that numerous changesand modifications in thedetails of the invention will be clear to those skilled in the art. Itis intended, therefore, that all such modifications and changes becomprehended within this invention which is to be limited only by thescope of the claims appended hereto.
